Coming off the POP to conceive

So in the middle of February I came off the progesterone only pill in order to get my cycle back on track to start trying for baby. This has not been something I’ve done before (coming off the pop) and I feel a bit confused as to what is going on with my cycle. I know it can take a while for things to return to normal (or a new normal) But we don’t want to get pregnant before all is established as I have fertility issues and so ideally need to have a good idea of a conception date.

I stopped pill and ovulated about five days later and before being on the pill I used to get my period 14 days after ovulation like clockwork. However. I am now a whole week past that and still no period. I did have some small amounts of spotting. But hardly anything. And I’m just concerned it may have been a period and I’ll start ovulating again without knowing when?

Or perhaps I am experiencing a lack of period as I heard this is also possible.

Has anyone got any experience with this to go off I would just like to feel a bit more informed
